[0023] Please refer to Figures 1 to 5 , now the medical cold compress device provided by the utility model will be described. The medical cold compress device comprises a mobile cabinet 10 and a cold compress pad 20; the inside of the mobile cabinet 10 is provided with a refrigeration machine, and the refrigeration machine has an external discharge pipe 11 for outputting refrigerant and a return pipe 12 for returning refrigerant; the cold compress pad 20 comprises a main body part 21 and a headrest part 22 connected to one end of the main body part 21; the main body part 21 is provided with a first refrigerant pipe 210, and the headrest part 22 is provided with a second refrigerant pipe 220; one end of the first refrigerant pipe 210 and one end of the second refrigerant pipe 220 are both connected to a first reversing valve 30, the first reversing valve 30 is connected to the external discharge pipe 11, the other end of the first refrigerant pipe 210 and the other end of the second refrigerant pipe 220 are both connected to a second reversing valve 40, and the second reversing valve 40 is connected to the return pipe 12; wherein the first reversing valve 30 and the second reversing valve 40 are used to cooperate to switch the passage to form a pad state of the first refrigerant pipe 210 flowing through refrigerant alone, or a head state of the second refrigerant pipe 220 flowing through refrigerant alone, or a full pad state of the first refrigerant pipe 210 and the second refrigerant pipe 220 flowing through refrigerant simultaneously.
[0024] It should be noted that the mobile cabinet 10 in this embodiment can be a cabinet with Forma wheels installed at the bottom, and hooks are arranged on the side wall of the mobile cabinet 10. The external discharge pipe 11 and the return pipe 12 are connected to the first reversing valve 30 and the second reversing valve 40 by quick plugs. After use, the quick plugs are pulled out for coiling and hanging on the hooks. At the same time, the cold compress pad 20 is folded or coiled (preferably coiled to avoid damage to the refrigerant pipe due to excessive bending) and placed in a containing space above or inside the mobile cabinet 10, thereby facilitating transfer. Thus, the continuous use requirements of patients on different beds can be met.
[0025] A refrigeration machine is a machine that transfers heat from a lower temperature object to an environmental medium to obtain cold energy. The heat transferred from the lower temperature object is commonly referred to as cold energy. The working medium participating in the thermodynamic process change (energy conversion and heat transfer) in the refrigeration machine is called a refrigerant. In this embodiment, the required refrigerant output temperature is obtained by heat exchange between the refrigerant and the coolant such as water or cooling liquid. The refrigeration machine itself is a prior art device, and its working principle will not be described in detail here. In this embodiment, the refrigeration machine is directly integrated and installed on the mobile cabinet 10 to facilitate transfer.
[0026] In this embodiment, the first reversing valve 30 and the second reversing valve 40 can be multi-position three-way valves. Different passage positions are formed at three positions. Specifically, there are two passage positions in which the external discharge pipe 11 and the return pipe 12 are connected to only the first refrigerant pipe 210 or the second refrigerant pipe 220, and one passage position in which the external discharge pipe 11 and the return pipe 12 are connected to both the first refrigerant pipe 210 and the second refrigerant pipe 220 (the first refrigerant pipe 210 and the second refrigerant pipe 220 form a parallel structure).
[0027] In this embodiment, the first refrigerant pipe 210 and the second refrigerant pipe 220 can be metal hoses or PVC hoses. Considering storage, PVC hoses are preferably used. If metal hoses such as aluminum pipes or copper pipes are used, the cold compress pad 20 should be coiled for storage. In this embodiment, the cold compress pad 20 can be filled with a cold storage gel, and the first refrigerant pipe 210 and the second refrigerant pipe 220 are wrapped with the cold storage gel. Thus, not only can the entire surface of the cold compress pad 20 obtain a low temperature to increase the cold compress area, but also the cold storage effect of the cold storage gel can reduce energy consumption. On this basis, considering that the human body gravity compression may cause the first refrigerant pipe 210 and the second refrigerant pipe 220 (in the case of using PVC hoses) to be flattened and affect the smoothness of the refrigerant flow, the cold compress pad 20 in this embodiment can be filled with a supportable sandwich cotton layer, and the first refrigerant pipe 210 and the second refrigerant pipe 220 are arranged on the grooves in the sandwich cotton layer.
[0028] Compared with the prior art, the medical cold compress device provided by the embodiment integrates the refrigerating machine in the moving cabinet 10, the first refrigerant pipe 210 and the second refrigerant pipe 220 are connected with the exhaust pipe 11 and the return pipe 12 of the refrigerating machine to form circulating refrigerant, so that the main body 21 and the headrest part 22 of the cold compress pad 20 can keep continuous and stable cold compress temperature during use, which is beneficial to improve the cold compress effect, and the temperature of the output refrigerant can be adjusted by adjusting the refrigeration power of the refrigerating machine, so as to meet the flexible adjustment of the cold compress temperature; the first refrigerant pipe 210 and the second refrigerant pipe 220 are connected with the refrigerating machine through the first reversing valve 30 and the second reversing valve 40, the first reversing valve 30 and the second reversing valve 40 are switched to make the first refrigerant pipe 210 or the second refrigerant pipe 220 flow the refrigerant alone, or make the first refrigerant pipe 210 and the second refrigerant pipe 220 flow the refrigerant at the same time, so that the corresponding compressing state, the head compressing state or the full compressing state can be selected according to the part to be compressed, which is not only beneficial to improve the application range and convenience, but also saves time and further improves the use convenience without pre-cooling.
[0029] In some embodiments, referring to Figure 2 , the first reversing valve 30 and the second reversing valve 40 are respectively embedded at one end of the main body 21 and the headrest part 22, and are respectively located on both sides of the headrest part 22. Since the first refrigerant pipe 210 and the second refrigerant pipe 220 need to be connected to the first reversing valve 30 and the second reversing valve 40, the first reversing valve 30 and the second reversing valve 40 are respectively arranged on both sides of the headrest part 22, so that the first refrigerant pipe 210 and the second refrigerant pipe 220 are conveniently connected.
[0030] As a specific embodiment of the first reversing valve 30 and the second reversing valve 40, please refer to Figure 4 and Figure 5 , both of which include a valve body 31 and a valve core 32; the valve body 31 is embedded in the main body 21, the center of the valve body 31 is provided with a circular valve cavity 311, the side wall of the valve body 31 is spaced apart along the circumference and is provided with two valve holes 312 communicated with the valve cavity 311, the two valve holes 312 are respectively used for connecting the first refrigerant pipe 210 and the second refrigerant pipe 220; the valve core 32 is sealingly and rotatably connected in the valve cavity 311, the center of the valve core 32 has a distribution cavity 321, the side wall of the valve core 32 is spaced apart along the circumference and is provided with two distribution holes 322 communicated with the distribution cavity 321, the interval angle of the two distribution holes 322 is equal to the interval angle of the two valve holes 312; wherein the distribution cavity is used for connecting the exhaust pipe 11 or the return pipe 12; when the valve core 32 is rotated to align and communicate one of the distribution holes 322 with one of the valve holes 312, the compressing state or the head compressing state is formed; when the valve core 32 is rotated to align and communicate the two distribution holes 322 with the two valve holes 312 respectively, the full compressing state is formed.
[0031] Specifically, the valve core 32 has a cover plate 323 for sealing the liquid separation chamber. A rotary joint is provided on the cover plate 323. The rotary joint on the first reversing valve 30 is connected to the external pipe 11, and the rotary joint on the second reversing valve 40 is connected to the return pipe 12.
[0032] The first reversing valve 30 and the second reversing valve 40 form a rotary valve structure based on the rotational cooperation between the valve body 31 and the valve core 32. By rotating the valve core 32, the valve body 31 and the valve core 32 can be rotated to form a rotary valve structure. Figure 5 The two valve holes 312 and the two distribution holes 322 shown in a are aligned one by one, so that the refrigerant can flow through the first refrigerant pipe 210 and the second refrigerant pipe 220 to form a full-coverage state; the valve core 32 can also be rotated to the right in the full-coverage state position as shown in FIG. Figure 5 As shown in the middle b, one of the valve holes 312 is aligned with one of the distribution holes 322, the other valve hole 312 is blocked by the peripheral wall of the valve core 32, and the other distribution hole 322 is blocked by the inner wall of the valve cavity 311, so that the first refrigerant pipe 210 can flow refrigerant alone to form a body application state; the valve core 32 can also be rotated leftward in the full application state to the position as shown in the middle b. Figure 5 The single valve hole 312 shown at c is aligned with the single distribution hole 322, so that the second refrigerant pipe 220 can flow refrigerant alone to form a head application state; on this basis, the valve core 32 can also be rotated to Figure 5 The two valve holes 312 and the two distribution holes 322 shown at d in the middle are not aligned, so that the first refrigerant pipe 210 and the second refrigerant pipe 220 are both in a closed state, thereby avoiding leakage of the refrigerant remaining in the refrigerant pipe after the external exhaust pipe 11 and the return pipe 12 are separated from the two reversing valves.
[0033] For some possible implementations, see Figure 2 and Figure 3 The headrest portion 22 includes a pillow pad 221 and a compress 222. The pillow pad 221 is connected to the main body 21, and the compress 222 is connected to the end of the pillow pad 221 away from the main body 21. The compress 222 is designed to wrap around and adhere to the forehead. A second refrigerant tube 220 is provided within both the pillow pad 221 and the compress 222. During a head compress, the pillow pad 221 can be used to apply a cooling effect to the carotid artery while the compress 222 can be used to cool the forehead, thereby enhancing the effectiveness of the head compress.
[0034] Specifically, such as Figure 3As shown, the pillow 221 is connected with two strips of compresses 222 extending to its two sides, and the two strips of compresses 222 are overlapped and adhered by magic tape. Considering that the compresses 222 need to be attached around the head, the compresses 222 are thin, and therefore, the two compresses 222 are overlapped to form a double-layer structure, so as to ensure the cold compress effect of the compresses 222, and on this basis, the overlapped area of the two compresses 222 is adhered and fixed by magic tape, so as to ensure the stability of the attachment of the compresses 222 on the forehead.
[0035] It should be understood that, in the embodiment, as shown in Figure 2 , the first refrigerant pipe 210 and the second refrigerant pipe 220 are both extended in a serpentine shape. The serpentine extension can maximize the coverage of the main body part 21 and the headrest part 22, so as to ensure the overall temperature balance of the main body part 21 and the headrest part 22.
[0036] In some embodiments, as shown in Figure 1 , the mobile cabinet 10 is provided with a controller 13 and a temperature sensor 14, the temperature sensor 14 is connected to the return pipe 12 and electrically connected to the controller 13, and the controller 13 is electrically connected to the refrigeration machine. The temperature sensor 14 detects the temperature of the return pipe 12 in real time and feeds back to the controller 13, and the controller 13 controls the output power of the refrigeration machine, so that the temperature of the return pipe 12 is kept within the set range, thereby ensuring the continuous and stable cold compress effect of the cold compress pad 20.
[0037] It should be noted that, as shown in Figure 1 and Figure 2 , the end of the main body part 21 away from the headrest part 22 is connected with a bandage 211, which is used to bind the cold compress pad 20 wound into a roll. When the cold compress pad 20 is used and stored, it is wound from the end of the headrest part 22, and finally the main body part 21 wound into a roll is bound by the bandage 211, so as to ensure the stability of the winding state and facilitate storage.
[0038] It should be noted that, as shown in Figure 1 , the mobile cabinet 10 is provided with a containing box 15, which is used to store the cold compress pad 20 wound into a roll. Placing the cold compress pad 20 in the containing box 15 of the mobile cabinet 10 can avoid occupying additional external space, which not only saves the overall storage space, but also facilitates transfer.
[0039] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
